What Amount of Solar Energy is required to charge an Ev?

If you are looking for an electric vehicle (EV) or already use one, it is most likely that you will have to install an EV charging station at your house. These home charging stations enable you to charge your vehicle at home. Therefore, you don’t have to find a charging station in public. The number of public EV charging stations is far less as compared to petrol pumps. Therefore, EV users mostly have to build their own.

If the energy used by EV charging stations at home is taken from the grid, it becomes costly. Its utilization cost is the same as that of ordinary home electricity use. It may be very expensive considering that an electric car stores a vast amount of electricity. Therefore, charging an EV with solar energy is the best choice for users as well as vehicles.

To determine the number of solar plates required for charging your EV, consider different characteristics. For example, the efficiency of solar plates, size of EV battery, hardware type, etc.

Solar plates and EV charging station

Combining solar panels for electric cars with an EV charging station offers numerous benefits. Not only are the energy production and usage costs lower, but the entire setup is more sustainable. Solar energy software plays a crucial role in optimising this process by ensuring that your solar panels generate enough energy to charge your EV efficiently. Solar inverters are essential in this setup, converting direct current (DC) from the solar panels into alternating current (AC) used by your EV. Once the charging port is connected to the inverter, it draws energy and transfers it to your EV’s battery.

How many solar plates are needed for an EV battery to charge?

The size of your EV battery decides the number of solar plates required. In this case, let us consider the 75 kWh battery of the Tesla Model S.

In the first step, we examine the amount of energy manufactured by each plate. This energy amount is evaluated by size, quality, efficiency, etc. 

A solar panel of 250 watts produces 30-42.5 kWh AC each month. To be safe, let us choose the bare minimum. If one affordable solar plate produces 1 kWh AC each day, then you will need 75 solar plates to fully charge the Tesla Model S daily.

However, 37 miles each day is the average distance covered by any motorist. This is equivalent to the power of 12 kWh. For this, 12 solar plates will be enough. If the efficiency of your solar plates is fine enough, then this amount can be reduced even more. Moreover, if you travel a few miles each day then this amount can be decreased even more. If your solar asset management is optimized, you may need even fewer panels, making this setup more affordable as most solar panel systems consist of 25-30 panels.

How much time is taken by solar panels to charge an EV?

The time to fully charge an EV depends on the battery size, efficiency, and voltage of solar plates. Let us consider a solar module system of 4kW and a battery of size 54kWh. A solar module system of this size generates around 3400 kWh yearly or 9 kWh daily. 

According to these assumptions, six 4 kWh solar plates will fully charge an EV battery. However, because most drivers do not drive more than 37 miles a day, it is unlikely that you will have to charge your EV daily to maximum capacity. 37 miles is equivalent to 12 kWh. As most systems have 25-30 solar plates, the original charging time will be less. 

Number of solar plates needed to charge Tesla

Electric cars and solar panels are great initiatives against energy dependence. Charging a Tesla with solar plates is especially encouraged. Tesla or any other EV can also work to store solar energy. Try to look for the cost of solar plates in your vicinity. The combination of EV and solar panels brings two great solutions in one room.

Now that you know that Tesla is a clean energy vehicle, we will explain what effect it has on carbon-conscious house owners. How to link solar plates to EVs? What amount of electricity will charge the Tesla Model S? The time to fully charge also depends on the model and link type. Moreover, a trip of 25 miles each way will need around 17 kWh of energy while only 2-3 kWh of energy is needed to run errands. On the other hand, 5 days are required to fully charge NEMA 5-15 outlet having 120 amp 15 volt breaker. Furthermore, 10 solar plates are required to charge a Tesla.

Depending on your specific energy needs and the solar asset management software you use, the number of panels required may vary, but the setup is generally efficient and cost-effective.

What quantity of solar energy is needed to charge an EV battery?

There are different ways to evaluate the amount of energy an EV battery needs. The first way is to notice the charge utilized per mile. It is represented by kWh/100 mi. Another way is to notice the electricity amount that fully charges the EV. This thought is similar to thinking about the cost of filling the fuel tank of an engine vehicle.

The quantity of solar energy needed to charge an EV battery is directly proportional to the battery size. Normally, EV batteries can store from 25-100 kWh, This difference is determined based on the range that EV travels with a solo charge. For instance, Tesla Powerwall 2 and LG Chem RESU 10H store 10-15 kWh of electricity.

What amount of electricity will EVs use yearly?

The amount of electricity consumed by EVs daily, monthly, or yearly depends on the distance travelled. If you live in a city and have a car but you use it sometimes, the amount of electricity needed to charge an EV will be very low. And, if you live in a village and use an EV daily to go to work, more electricity will be required yearly.

An average Indian drives almost 13500 miles yearly. Thus, most EVs will need 5000 kWh of power yearly to cope with this much driving. 

Bullet points 

• 5-10 solar plates are needed for an EV that travels 40 or more miles daily.
• Electric vehicles are more affordable and efficient than the typical combustion vehicles.
• In the long run, energy generated by solar plates is cheaper and better than electricity from the grid.
• Mostly, public EV charging stations are more expensive than electricity from the grid and polluting at the same level. 
• Charging an EV at home through solar panels is better in terms of pollution control and saving money.

Result

Switching from fossil fuels to solar-powered EV charging benefits your savings and significantly reduces your carbon footprint. Although EVs may have a high initial cost, the savings on fuel and government incentives quickly offset this. The amount of energy needed depends on the EV battery size and daily travel distance. If you already have solar panels and plan to add an EV, a level 2 EV charger can be used with a 20-80 amp breaker. By utilizing surplus energy efficiently with solar software like Futr OS, you can optimize your setup even further.
